SPECIFICATION forming part of Letters Patent No. 766,541, dated August2, 1904.

Application filed October 12. 1903. Serial No. 176,685. (No model.)

To rI/Z-Z whom, it ntrty concern:

Be it known that I, FREDERICK MoLLnDoRE SPIEGLE, a citizen of the UnitedStates,and a resident of the cityof New York, borough of Manhattan, inthe county and State of New York, have invented a new and ImprovedRollerScreen, of which the following is a full, clear, and exactdescription.

The object of the invention is to provide a new and improvedroller-screen to r use on windows, piazzas, and other places desirableto be screened against flies, mosquitos, and other insects and arrangedto permit convenient and easy unrollingot' the screen for screeningpurposes, to allow rolling the screen up to be completely out of the waywhen not in use, and to prevent bulging of the screen when in use.

The invention consists of novel features and parts and combinations ofthe same, as will be more fully described hereinafter and then pointedout in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure l is a front elevation of the improvement as applied to a window.Fig. 2 is an enlarged sectional side elevation of the same. Fig. 3 is atransverse section of the same on the line 3 3 of Fig. 2. Fig. l is asectional plan view of the same on the line l 4 of Fig. 2. Fig. 5 is aperspective view of one of the bearings. Fig. 6 is an enlarged sideelevation of the spring locking device for the screen, part of the endbar being removed; and Fig. 7 is an enlarged rear sectional sideelevation of the operating mechanism for the locking device.

The roller-screen illustrated in Fig. 1 is arranged to screen orunscreen the lower half portion of a window; but it is evident that thedevice may be readily employed for screening the entire window or forscreening piazzas or other parts of buildings.

The casing A of the roller-screen, as shown in the drawings, is securedat its ends to the sides of a window-frame B, and in the ends of thesaid casing is jonrnaled a spring-roller C,

on which winds and unwinds a web D, of screen material, such as pliablewire-netting. The bottom of the casing A is provided with a slot A,extending lengthwise ot' the casing throughout its length, and throughthis slot passes the screen-web .l) to screen the lower portion of thewindow when the lower sash B thereof is raised.

The end of the screen is provided with a suitable cross-bar E, having aknob E or the like for conveniently pulling the screen-web down wheneverit is desired to screen the window, as mentioned.

The sides of the screen-web are provided .with fixed spaced bearings F,adapted to engage guidewavs Ur, secured to the sides of the window-frameB, the said bearings serving to protect the side edges of the screen-webagainst unraveling, to strengthen the screen-web, and to prevent thescreen-web from bulging by gusts of wind or the like at the time thescreenweb is extended to cover the window-opening.

Each of the bearings F is preferably made of metal and consists of ahead F and two members F F, engaging the screen-web at option G of theguideway G, which tubular portion is split on the outer side andconnected with side walls (i between which pass the members F of thehearing, as plainly indicated in Fig. 4, so that the screen-web 1) doesnot come in contact with the side walls of the guideway or any otherpart thereof.

It is understood that the head F of each bearing is somewhat larger thanthe space between the side walls G, so that the head F prevents sidewisemovement of the web D, and as both sides of the screen are engaged bytheir bearings F with the guideways Gr it is evident that the screen-webcannot bulge when subjected to a transverse strain, such as a gust ofwind or the like.

As the bearings F are spaced apart, it is evident that the frictionalcontact of the several bearings with the guideways is reduced to aminimum, so that it takes but little power on the part of the operatorto pull the screen 7 down and also little power of the spring in theroller C for turning the roller to Wind up the screen.

As the side edges of the screen between adjacent bearings F extendbetween the side Walls G of the guideways, it is evident that the saidside edges are protected and are not liable to unravel or be otherwiseinjured.

The guideways G extend with their upper ends close to the casing A, theslot A of which is in register with the openings in the tubular portionG, and the space between the side walls G and the end walls of thecasing at the slot A are preferably rounded off, as indicated in Fig. 3,to allow an easy movement of the screen-web through the slot A to theguideways Without creating undue friction or binding of the screen-web.

In order to lock the screen-web in any extended or unwound position, thefollowing device is provided: The shank E of the knob E is journaled inthe end bar E and carries arms E connected by wires or links E with thefree ends of spring-catches E secured on the terminals of the end bar Eand adapted to engage notches G on the inner edges of the guideways G,as plainly shown in the drawings. By turning the knob E in one directiona pull is exerted on the spring-catches E to disengage the same from thenotches Gr to unlock the screen-web-and to allow rewinding of thescreen-web by the revolving roller C or to allow of pulling thescreen-web down on the operator exerting a downward pull on the knob E.The links E extend from the diametrical arms E in opposite directions,and preferably within recesses formed longitudinally in the end bar E,as plainly shown in Figs. 6 and 7. When the screen-web has reached thedesired position, the operator releases the knob E, so that thespring-catches E by their own resiliency snap into adjacent notches G?to lock the screen-web in position and simultaneously on both ends ofthe end bar E. v

The roller-screen described is very simple and durable in construction,can be cheaply manufactured and readily applied to windows and otherdevices, and the screen-web can be readily unwound from its roller C forscreening purposes or allowed to wind up on the said roller to beinclosed in the casing A and be out of the way when not in use.

It is understood that the spring-roller O is of the usual construction,preferably of the Hartshorn type, so that further description of thesame'is not deemed necessary.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A roller-screen comprising a casing for attachmentto a window-frame or the like, said casing extending from one side ofthe Windowframe to the other and having a slot extending lengthwise inthe wall of the casing, a spring-roller journaled in the ends of thesaid casing, a screen winding on and unwinding from the saidspring-roller and provided at its sides with spaced bearings, eachconsisting of two members, fixed to opposite sides of the screen-web andheads on the outer ends of the members, projecting beyond thecorresponding side edge of the screen, and fixed upright guideways forthe bearings to slide in, each guideway having a split tubular portionfor the heads of the bearings and spaced side walls for the bearingmembers, said. side walls being extended and formed into return-bendsterminating at their extremities in flanges for securing the guides tothe Window-facing, the upper ends of the said tubular portion and thespaced side walls registering with the said casing-slot, at or near theends thereof, as set forth.

2. A roller-screen provided with a springroller, a screen-web Winding upand unwinding on the said roller and having an end bar,

fixed upright guideways for the sides of the screen-Web, provided withnotches on their inner edges, and a locking device on the screen-Webbar, comprising a knob mounted to turn, springs forming catches on theterminals of the end bar projecting outwardly therefrom and adapted tonormally engage the said notches and a connection between thespring-catches and the said knob, as set forth.

3. A roller-screen, comprising a screen-Web, guideways for the sideedges of the screen- Web, said guideways having notches, an end bar onsaid web, said end bar having a bearing, a locking device for thescreen-web comprising a knob mounted to turn in said bearing in the endbar, links extending from the knob in opposite directions, andangularshaped springs forming catches, each catch having one end securedto the end bar of the screen-web, and the other end connected with oneof said links, the said spring-catches being adapted to engage saidnotches on the guideways for the screen-web.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

FREDERICK MOLLEDORE SIIEGLE.
